Let K be a Galois extension of a field F with G = Gal(K/F). Let L be an extension of F such that with corresponding primitive idempotents , where Ni's are fields. Then G acts on transitively and . And, let R be a commutative F-algebra, and let P be a prime ideal of R. Let T = , and suppose there are only finitely many prime ideals of T with . Then G acts transitively on where qf() is the quotient field of . ⠌㔀 ؀㘴ㄮ㔻᠀䡯浥‭⁦慭楬礠浡湡来浥湴
